Germanium is not used in integrated circuits. Silicon is.
The metalloids silicon and germanium, also in Group 14,are used to make computer chips.
The two main elements used to make computer chips are germanium and silicon.
Silicon and Germanium are the elements used in transistors
Silicon is used in the manufacture of computer chips.
Not at all, except for the first few computers I used (which were built with discrete germanium transistors) every machine I used was built using silicon chips. If the first computer you used was in the 1980s or later, you probably never saw a machine that wasn't entirely silicon chips. Even the germanium transistor machines ran about the same as modern computers, except the I/O which was usually very mechanical.
computer's chips and contact are made with silicon.

It is not, silicon is. It is not possible to make ICs commercially using germanium (mostly because its oxide is crumbly and water soluble unlike silicon's oxide which is a stable and insoluble insulator, which means germanium ICs must be wired by hand under a microscope which is too costly for production). This means that germanium is limited to usage in discrete components (transistors & diodes) only. Some work is being done using silicon-germanium alloy for ICs, but it is not in the market yet.

Computer chips are made from silicon and sand that has a high quartz content. Computer chips help to store computer memory.
